As improvement, said sealing ring is located in the said groove, and said sealing ring shape is agreed with said groove shapes mutually.Guaranteed the sealing of the connection of transitional pipe segment, guaranteed that transitional pipe segment when connecting, seepage can not take place.
As improvement, the link place of said each transitional pipe segment is provided with two sealing rings, connects through sealing shroud between the said sealing ring.
As improvement, the centre position is provided with convexity in the said sleeve pipe, said protruding junction of inserting adjacent transitional pipe segment.
As improvement, it is characterized in that: said sealing ring is a rubber seal, has good sealing property and flexibility, when ground generation sedimentation, has certain non-deformability between the transitional pipe segment that links to each other.
As improvement, be provided with through hole in said municipal drainage pipeline junction on the said manhole, be provided with the water-swellable sealing ring between said through hole and the said municipal drainage pipeline.
As improvement, said through hole leading section is cylindrical, and rearward end is taper type, and said water-swellable sealing ring is located in the leading section of through hole, the diameter of the small end face of said frustum and said municipal drain to diameter match.
The beneficial effect that the utility model is compared with prior art brought is:
Go out the family drainage pipe and fix, increase the pipeline changeover portion and adopt and flexibly connect in outdoor manhole entrance with building self structure basis.The flexible transition section that this connected mode utilizes the sealing, retractility of multistage transitional pipe segment and rubber accessory to form guarantees good drainability when making this pipeline section that certain anti-sedimentation capacity arranged.Facts have proved that this connected mode effectively guarantees the performance and the safety of drainage pipe with less expensive, simple method in the subsidence range of expection.
